Antibacterial Geomembrane


Geomembrane is a very low permeable synthetic membrane which is used in various geotechnical engineering projects to control water or gas leakage. It has been confirmed that for this application, geomembranes are more efficacious than other traditional products such as concrete, asphalt, and compacted clay. This product has a wide range of properties, i.e. physical, mechanical and chemical resistance, to protect our environment and water resources. It is worth mentioning that the antibacterial activity of polymers reinforced with silver nanoparticles is stable and its high antibacterial efficiency has been observed against different species of bacteria. Silver ions and its compounds can kill a wide range of bacteria, while they have no toxic effect to the human body. Therefore, the use of silver in different forms is a common method of protection against bacteria. 


  • Drain for drinking water, liquid waste, etc.
  • Insulating coating in reservoirs for preserving and storing required water for agriculture and fish breeding

Advantage of Using Nanotechnology

The silver antibacterial activity remarkably increases with size reduction up to nanometer scale, in a way that they can kill more than 650 bacterial species. By decreasing particle size, the release of silver ions increases, which as a result improves antibacterial activity. Determining the antibacterial activity of this product was carried out by ISIRI 10900.
